Following a season that fell well short of expectations, Arsenal's busy summer continues with fresh reports of possible transfers.

With Gael Clichy gone, Kieran Gibbs appears to be the first choice at left back, but according to The Daily Mail, Arsenal are interested in Newcastle defender Jose Enrique for £8 million, while Everton's Leighton Baines and Blackburn's Martin Olsson are also potential candidates.

Long thought to be on his way out of Emirates this summer, The Guardian reported that Denilson has two clubs that are interested in the midfielder: Bolton Wanderers and Newcastle. Arsene Wenger is said to be still interested in Gary Cahill, so perhaps Denilson can me moved to Bolton so the Gunners can finally land their star centre back. Another option could be to include Denilson in a deal for Enrique.

Though Arsenal are expected to have a healthy Thomas Vermaelen back, and saw promise in Swiss-born Johan Djourou, central defense remains a major concern going into the 2011-2012 season. Other centre backs that remain on Arsenal's radar are Chris Samba, Phil Jagielka, and Scott Dann.

In late June, Daily Mirror reported that Arsenal had interest in Bayer Leverkusen attacking midfielder Arturo Vidal, but with Samir Nasri apparently sticking around, Wenger probably doesn't have much interest in spending £15 million when there are more pressing needs.

One player that won't be on Arsenal next season is Stewart Downing. Despite heavy interest by Wenger, Liverpool and Aston Villa reportedly agreed to a fee that will rise to £20 million for the left wing.

In what seems like a departure from previous strategy, Wenger has shown an interest in adding players who are in their prime. Most of the players that Wenger has targeted this summer have been in their mid twenties, including recent addition Gervinho.

Of course, Wenger's transfer strategy will truly be put to the test if Cesc Fabregas leaves, after endless rumours with his link to Barcelona.
